At one time or another we have all broken down be it on the trail or on the road. We all have made quick repairs to get us going again. I have one to share with you.
If you have a NP 229 X-case and your vacuum mode switch fails ( broken vacuum lines, failed motor, etc.) you can still engage 4 HI or 4 LO by:
1- Remove vacuum motor.
2- Remove mode adjusting rod from lever by unthreading.
3- Stuff you will need: one carriage bolt 5/16" X 6", two nuts, two 5/16" washers, two 1/2" washers.
4- Thread one nut to head of carriage bolt.
5- Add one 5/16" first and then one 1/2" washer.
6- Pass bolt through mounting hole that was used to hold vacuum motor.
7- Add one 1/2" washer then one 5/16" washer and thread nut about 4" from end of bolt.
8- Thread bolt into mode rod.
9- Thighten nut to take up slack on mode rod. Making sure that mode rod is fully engaged in 4 HI.
10- Tighten remaining nut to vacuum motor mount.
11- Do not take your mode selection switch out of 4 X 4.
You are now stuck in 4 X 4 and should be able to shift your range rod from 4 HI to 4 LO with no problems. Include this hardware with your truck. You never know when you may need it again.
Anyone else have any good fixes?
